To all whom it only concern: I Be it known that l, SAMWL H. Tiusimu, acitizen of the United States of America, and resident of Fort Madison,Lee county, lows, he s invented a cert-eiunew end useful Improvement inPlanters, of which the following is a. specification.

My invention relates to planting ine'chines in general, but moreparticularly to machines for plentin 'corn, and especielly to shut areknown c reek-row corn plan ters.

Generally stated, the object oi'xuny iuvcntion is the provision of oniinnroved and highly eiiicient check-rev: planting nieehij A specialobject of my invention is to provide improved means'for utilizing thefor ard motion of the oleni'er for operating the seed-droppingniecuunism, the check-row Wire being, used only for starting the saidmechanism, and the check-row forks, nrelcrebly one at each end ofthesecd shaft, being driven interruptcdlyby power,derived, preferably,from one of the ground -Wheels through the medium e mutilated syuoeketgearing, uhereby the irensniissioiii ol. poser is automaticallyinterruoted as soon the 'inutilu-ted portion of the sprocket Wheel comesin contact with the sprocket chain,

and whereby vthe rotary seed dropping mechanism then remains inactiveuntil unother knot on the chock-row ivirc strikes thev fork,theengzigeniont of the said knot with the fork serving to move themutilated sprocket wheel a. distuuce sullicicut to bring its teeth intoengagement with the sprocket chain, end the engagement of the iork withthe knots on. the checlerow wire each time accomplishing a two-foldpurpose, namely the starting or the rotary seed mechanism to'(lischu'rge into the spout or boot of the runner u definite number ofseeds or kernels fiith the discharge from the said spout or hoot of theaccumulation of seed or corn therein brought ziboutbythe previousoperation of the seed f Another-object of my invention is to provideimproved means for varying the speed of rotation of the secd-droppinmechanism, suid means involving, as iii 1 memes more fully appear, aplurality of bevel pinions of, difi'erent sizes on the seed shaft, end

iustruinentulities -whereby any one of said puuons may he brought intoengagement with szud seed-droprung .ruechemsni, thus giving u variablerote of discharge from the Specification oi Letters Patent.

The pole is also connected withthe said axle by means of per-el l frame members D, which have theirends orought together and secured to the pole at (Z. The two runners orfurrow openers E are arranged, as usual, in

oi the seed-dropping mechanism Lo :u-compivotully mounted upon the poleand germ iii vided with a small crank arm 7t, connector by a link 72with the bar or box rail 6, in the manner shown. it will also be seenthat this hand lever is connected .by a link k with ,thecr k arms Frmounted upon the rock rack It" is secured to the shit r id to c siredposition. 7, sl 9 runners and seed boxes or hoppers l, hxillCll latterare mounted on the 1 minus, can be raised and lowered will seen that theoperating shaft 1* is provided at each. end with the usual fork orcheclorow arm f, whieli'arms or forks are, however, rigidly secured tothe said seed shaft. The box rail 6 is novidcd with lor y-ezrtendingarms c upon which are mounted the usual guide rollers c" and c forguiding the cheek ow wires through the said forks or check-row arms. Ateach side of the inacl'line the operating shalt l provided with threebevel pinions e 12 and c which are diter'ent diameters and adapted todrive the seed mecl of speed. This shaft is also provide il at one sideof the machine with the mutilated gear or sprocket wheel J, the samehaving pre'lcrably but a few teeth, substantially as indicated in Fig.6. In thisway, said sprocket wheel has its periphery provided with teeth"for only a portion ct its circumlerence, and is left smooth for theremaining portion tl roof. Each seed hex has a downwardly 'e;-;- tendingspout or boot ii ich extends to the heel or rear portion of is allottedrunner. The corn is contained in the two seed boxes I, and i'lischargrotl'ierclrom is'controlled by an uitable mecl iai. sin at different ratesi i, iauism operated b [no seed shaft.

The hove pinions 0-, and c are adapted to engage tne bevel gears N forthe purpose of driving the rotary seed plate oi each seed mechanism,which plates may be of any suitable character. Each group 0i bevelpinions is adj stable as a unit along the shaft, whcrcljiy any member ofsuch unit can he caused to enga e hovel gear of tlic adjacent orassociated seed mechanism. 'lbc bottom oi each hopper is hold in placeby a bolt 0, as illustrated, which bolts have thumb-nuts. Suppose thathigh speed is desired for the said seed-dropping lll -3l1:iilism, forthe purpose oldropping a large number of 'lc ruas of corn in. each hill.in icl case, the piuions are so :uljustcd that the pinionsc engage bevelgears, as shown in Fig. ll. mzcomplishod by witl'nlrawing the in is andtiltingup the said boxes (it bein rvcd that tlubolts 0 permit the upwardsv- .nging motion oi the hoppers) until the said pins can he reinsertedin. the uppermost ol tln three holes l 2 and 3, with which he upper endol earl: s; out

ate with the usual andlovor in l l l i l l l l i l senses Then the bolt0 can he tightened,

the other land, should. a lower speed be desired, ne as to drop only afew kernels of corn in cam hill, the said bevel pinions can then headjuste fl in such manner as to bring the pinions a into engagement withthe said bevel gears, as shown in Fig. 10. justment, it will heobserved, is obtained by withdrawing the said pins '0" and reinsertingthem'in the lowest hole 3 of each spout. In this way, the quan y of seeddeposited-in each hill can be varied easily and quickly; 1 The sprocketwheel J is connected with the ground wheel at one side of the machine bythe sprocket chain it, the sprocket Wheel 71 being connected with saidground Wheel in any suitable manner. l Yith this arrangement, thechock-row wires are adapted to engage the forks or checlorow arm f, andthereby rotate the shalt F just enough to bring the first tooth 0isprocket wheel J into engagement with. the sprocket chain, which latterhas been. running idle. Power is immediately communicated from thesprocket chain to the shaft F for the purpose of rotating the seed ringsof the seed-dropping mechanisms, and also for the purpose of actuatingthe usual valves in the spouts or boots of tlic runners, thusdischarging a quantity of seed at each side of the machine. When theshaft l made substantially a full or comple e rotation, the teeth ofsprocket wheel d become disengaged from the sprocket chain, thusdiscontinuing the transmission of power fro the seed inccl'ianism. Inthis wheel is used to r positively driving the seed mechanisms, hut atthe same time the This adin the ground to way a ground chcclcrow wiresand arms are used :lor 0011- u 7 y the power communicated from theground wheel. The knot, of course, leaves the ll1(.(il\'-l'()W armbol'ore the seed mcclninis are through operating; lio seed sliz'il'ttlius rotating untillho mutilulod purl" olthe sprocket comes in contactwilli the chain, and the said check row arm is thus stopped and leftpointing downwurdly and in position to he engaged as soon as anotherknot is (-llCOllIltOlCil in the llaclitinma l-cnotstrilcos the fork l wethings are accomplished to wit, the Hlol'llhg o! the rotary seedmechanism, and

I anism continues-to operate the corn continuously, by 1ng an ordinarysprocket wheel for the muti the dischar e from the spout or boot of theseed or corn accumulated therein by the previous operation of the seedmechanism. Thus the knots on the check-row u' 'ire mark the positionsfor the hills of corn, and also mark the points at which the rotary seedmechanisms are started. Each seed mechand drop the required number ofseeds or'kernels of corn until the smooth portion of thosprocket wheelengages the chain, and then the drop- I ang of the seed .or corn intothe s outs or ed upon a seat bar T secured to the tongue.

. It will be seen that with my improved arrangement the chain is neverout of contact with the mutilated sprocket wheel, and that the action iscertain and positive, the trans mission of power for the round wheelbeing 'interru ted at the ire er time and the reestablishing of. thetransmission being certain and sure as soon as the revolving fork on thesaid siaft again thrown over by the check-rev wire-that is to say,as-soon as I the sprocket wheel is again turned s'ufliciently to bringits teeth into engagement with the, chain.

' For the broader purposes of my invent! on, any suitable form ofmutilated gearing may be used, but I prefer to employ a mutilatedsprocket gearing, as i find that it hasa distinctadvantage over otherforms, for vari- Forexaniple,should the chain ride up onto the end of asprocket tooth, when the mechanism is started, no strain or orealmgcwill occur, as the sprocketchain can have sutlicient slack to enable itto do so without straining or breaking any of the parts.

axle in the medium of running. over a mutilated sprocket gearing,

l find that the desired result is. obtained mtertering 111 any way withthe 1 without raising and lowering of'the planteryas the sprocket chainis flexible and readily permits such raising and lowering of the runnersand noses at the front'of the planter. Also, and for thebro'aderpurposes of my invention, the sprocket chain can be connected inwheel-that is to say, itneed not be directly connected therewith, theinclusion of the transmission between Furthermore, with a sprocket chainany suitable manner: with the ground I apprehend, be within the scopeand spirit of my invention; but there vantages in the direct connectionto the hub of the wheel, -which is loose on the axle, as, for example,this permits the axle to form a part of a rigid frame between the wheelsand box rail. As the rear ends of the reaches V are enlarged where heyupon the square portion of the axle, they prevent one runner fromrisingwithout the other; and, also, the Wheels are held in alineincntwith the runners. Except where so specified, however, I do not limitmyself in the claims to a direct connection of the sprocket gearing withone of the ground wheels.

I claim:
